Ok, I've got a problem

How do you do this?

The problem - g(f(x)) where g(x)=x^(3/4) and f(x)=4x^-5

I get the concept for the most part, but my answer keeps on coming out wrong. The correct answer according to my book is 2^(3/2)x^(-15/4)

I need to see detailed work with explanations please. I need to find out what I'm doing wrong.

Thanks:)

Edit - nvm, got it off yahoo answers.

Here's how to do it if anyone is interested:

g[f(x)]
[4 x^(-5)]^(3/4)
0= 4^(3/4) [x^(-5)]^(3/4)]
0= (2?)^(3/4) x^[(-5) . (3/4)]
0= 2^[2 . (3/4)] x^[(-5) . (3/4)]
0= 2^(3/2)] x^(-15/4)

2^(3/2)] x^(-15/4)
